– The unique stainless steel sleeve with external lock
The new ray of hope for underground repairs
Obduramus Umwelttechnik GmbH is active in the field of environmental engineering and develops and produces solutions for sewer rehabiliation. Our products provide solutions for a very diverse range of damage types within pipes.
Conventional sewer rehabilitation methods (digging) can present significant challenges for local authorities, as well as their contracted consulting engineers and repair organizations. For example, if important transport infrastructures are impacted by construction, coordination costs can be considerable.
Obduramus has developed alternative trenchless repair solutions which reliably and permanently seal pipe damages internally. Our Circum technology consists of a stainless steel sleeve surrounded by an EPDM rubber seal, both to be pressed against the inner pipe wall via an inflatable packer until sealing occurs and then to remain permanently locked in place by a strong mechanical lock. Different sealing processes and diameters are available. With this trenchless system a damaged pipe can be repaired within minutes, instead of many hours or several days.
Their benefits:
Permanent sealing purely based on the principles of mechanics
Effective and sustainable repairs
Stainless steel sleeve manufactured using the same grade of steel for all components, resulting in no corrosion
Fast and simple installation saves time
Installation with no environmentally harmful chemicals
The stainless steel sleeve with external lock
Quick and sustainable
Trenchless pipe repairs
Our environment, and especially our groundwater, are very sensitive systems which must be protected. Leaky pipes can cause a variety of damages and also potential harm, which may be very expensive to fix. We offer comprehensive solutions for effective and sustainable rehabilitations.
For small and large diameters
Optimum adjustment
Due to its patented lock, which lies flat against the pipe walls, these internal sleeves adapt perfectly to the contours of the internal pipe walls. This ensures minimal cross-sectional reduction in the pipes and also prevents passing impediments from becoming lodged.
Innovative, efficient and reliable
